Cimicifuga racemosa(CR) is a North American perennial
herb that grows on higher elevation hillsides and in woodlands(1). The rhizome
is broad and creeping, producing stems up to 9 feet tall. The ovate or oblong
leaflets range in size from 1 to 6 inches long and 4 inches wide, while the
smaller leaflets are ternate, then pinnate, and sometimes further split. From
May to August, little, white, fetid flowers appear in lengthy racemes. The
rhizome is the plant part used for therapeutic purposes(1). It is commonly
referred to by several names such as black cohosh, bugbane, rattle weed,
snakeroot, squaw root, or rheumatism weed(2). CR has been the subject of
extensive clinical investigations due to its widespread utilization among
elderly women as a symptomatic alleviation for postmenopausal symptoms—an
alternative treatment option to estrogen therapy(3)
